Why WAN optimization is important to consider during this economic climate?

Thumbnail image for Thumbnail image for internet_network.gif

As 2009 winds down, most enterprises who follow the standard calendar fiscal year, are typically in budget planning mode if not already finished for 2010 spend. 

Indeed, we have seen some hestitation or delay in some investments this year.  A more popular request of late is that enterprises are requesting more OPEX based services rather than adding CAPEX to their end of year bottom lines.  WAN optimization remains a technology area still in demand given the changes of focus on consolidation and virtualization, which are common areas for quicker cost reduction around IT but where maintaining performance remains a challenge. 

Managed WAN optimization provides many financal benefits while offloading the need for up-front capital.  Taking advantage of all the capabilities that WAN optimization provides - traffic shaping/QoS, compression, acceleration, and caching - enables better return on application usage and end-user productivity. 

We are seeing upwards of 50% increase of application performance response times for some enterprises who have experienced degradation especially following a server or data center consolidation. 

Additionally, managed WAN optimization has enabled double-digit TCO savings on the network and IT for enterprises out-tasking the management of such infrastructure.  Being able to take advantage of such numbers that WAN optimization can enable, makes it more interesting for enterprises to move sooner rather than waiting out the economic situation.

I invite you to review the following whitepaper which highlights and end-to-end approach and benefits to WAN optimization.

Four point plan to reduce IT costs

ITBusinessEdge highlighted "four simple ways to reduce tech support and help desk costs", intended to aid companies looking to "trim the fat" by reducing operating expenses. In addition to any cost savings, the moves will improve systems uptime, enabling non-IT staff to concentrate on their work rather than being slowed by computer problems, and also improves user satisfaction, again through the removal of the need to address IT niggles.

The four points, as suggested by Scott Gordon, Chief Operating Officer of US IT support company Dataprise, were:

  • Keep users informed. Provide advance warning of scheduled downtime or planned maintenance, including projects undertaken outside of working hours, and with regular updates on unforeseen problems. This will reduce the number of calls made to tech support, enabling IT staff to focus on projects in hand or on rectifying problems, which is a more effective use of resources.
  • Outsource some (or all) technical support tasks. This provides obvious benefits, including the flexibility to add extra support when needed, without having the costs incurred by additional staff during quiet periods. It can also reduce overtime costs for in-house staff, by spreading the IT support load over a larger number of workers.
  • Invest in regular maintenance. Regular checks such as updating anti-virus definitions, performing back-ups, and applying hotfixes and software patches has an impact in terms of time and money during the short-term, but can protect against future issues which would incur far greater costs in terms of problem resolution.
  • And, finally, take advantage of automated tasks. Adding an IT FAQs section to the corporate intranet, addressing some of the most commonly raised problems, can save IT staff a significant amount of time which would otherwise be spent rectifying routine issues problems, for example resetting passwords.

Good news: IT spending out of step with economic cycle


flower.gif
When IDC forecast global IT spending earlier in the year would remain the black, it did not foretell the utter collapse of the IT industry. Instead it suggested that while demand will be down in all regions it would not be catastrophic. Seemed odd at the time - surely, IT spending would mirror the general economic trends and head south very quickly.

Well according to venerable IDC chief analyst John Gantz, speaking at Orange Business Live in London, the IT spending cycle doesn't always follow economic cycles. With decades of experience, Gantz pointed out that that the current economic crisis is not necessarily leading to a crunch in IT spending. The last great depression in IT was 2001 (remember the dotcom bubble, satellite bubble and expensive 3G license fees?) yet the general economy was not suffering at the time. 

According to Gantz, to assess the impact the economy will have on ICT spending, we need to take the long view because IT spending cycles are singing to a different tune. Looking at the US economy over the last 50 years, and the IT spending during the same period, Gantz said "1982, a bad year for the economy, a great year for IT. 1984 was a great year for the economy, a bad year for IT. The same in 2002, a mild slowdown in the economy, a disaster in IT. In fact the biggest IT collapses have NOT coincided with the biggest economic collapses, but instead have been part of a long term IT boom and bust cycle." IT has its own cycles and fortunately we are in the right part of the bell curve to be facing a financial crisis. "Without knowing it, we have been getting ready for a crisis for 5 years. No need to freak out," he said.

Echoing Forrester's Mike Cansfield earlier in the day, Gantz also believes that this is the ideal time for companies to leverage IT to transform their business. "I think the real impact of the economic crisis will be as an agent for change. Change that might not always be pleasant.as far as I can see no company transforms itself willingly. Usually it's only under threat and duress. Schwab's threat from Etrade, Merrill Lynche's threat from Schwab. Microsoft's threat from Netscape. British Airways threat from Ryanair."

Gantz identified some key technologies that companies should be using to transform their business and resist newcomers. These include: 

  • Security management
  • Mobile data
  • Enterprise social media
  • Business analytics
  • IT outsourcing & BPO
  • SaaS
  • Virtual machines.
  • Search and discovery
  • Storage replication
  • IT automation

And his recommendations for technologies/ issues to watch were:

  • Visualisation management software
  • Real-time analytics
  • Ethical hacking.
  • IT-driven sustainability
  • Location-based services
  • Video search
  • Compliance
  • Reputation management software
  • M2M

Improving the efficiency of IT infrastructure

This buzz session at Orange Business Live looked at how to improve the efficiency of the IT infrastructure and was led by Jean Critcher, Solution Director Orange Business Services. 

The current economic crisis is affecting most investment decisions, and research from analyst Gartner identified that improving business processes and reducing costs were the two most important business priorities for CIO at the moment. The session identified four key areas that can help CIOs in this regard. They were IT infrastructure optimization, virtualization and cloud computing, selective outsourcing and M2M.

Critcher stressed that it's no longer enough just to optimize the network because all parts of the infrastructure can affect the performance of key business processes - including the data centre, applications, storage, etc. Application acceleration is the latest trend in current WAN optimization processes with many companies particularly interested in optimizing Web 2.0 applications. Orange customers have had much success with WAN optimization including:

  • Tobacco manufacturer: used application performance management to offload applications such as mail into the Internet to free up the IPVPN for critical apps. It managed to achieve 80% more usage from the IPVPN with this approach
  • Lenovo: used WAN optimization to increase its WAN capacity three-fold at no extra cost
  • Leading hotel group: used WAN optimization to give it 99.9% uptime in applications and reduced its TCO by 27% through outsourcing

 The next speaker, Rob Hodgkinson, introduced cloud computing to the audience. He said that two main types of cloud computing were emerging: software as a service (SaaS) and infrastructure as a service - which he also dubbed platform as a service (PaaS), and said that Orange was more interested in the latter. Basically cloud computing is a scalable, opex-centrix model, which is accessed over the Internet.

Most cloud computing services are currently targeted at small businesses, such as Amazon Web Services, and there are a number of issues that need to be sorted out before they are a viable option for corporates, including SLAs and penalties, security and internal business processes. For example, rapid provisioning in cloud computing is pointless if the internal process for provisioning computing power is a bottleneck.

Orange has an ambitious plan for cloud computing services and already offers basic cloud servers. By 2010 it plans to offer a virtual cloud based data centre that can be automatically provisioned over the Web.

The final part of the session was on M2M, and the main theme was that M2M is ready for deployment right now, and that many Orange customers have already achieved substantial business benefits from it. Basically M2M helps companies optimize their business processes, and even in some cases create entirely new business models. Examples include:

  • The Belgian railways that used M2M to track its locomotives, helping it locate resources and prevent accidents;
  • Singapore Port Authority that is able to move twice as many goods through M2M;
  • Gefco, which saved 5% of its fuel bill by better route optimization.

We have carried out exclusive video interviews with all of the above speakers and they will be available in due course.

Plan your way out of recession

Interesting keynote from Mike Cansfield, principal analyst at Forrester Research, to kick off this years Orange Business Live. Mike reckons that all companies should now be focussed on planning their way out of the recession (and yes, it is a recession, not a depression as the doom mongers are proclaiming.) Not all sectors and all markets are recessed, so look for areas of growth, he says such as Africa, Middle East and China.

It's also vital to review the underlying cost structures pervading the whole business and recognise how new technologies like Cloud Computing, SaaS, M2M, telepresence, can strip out costs that companies have so far overlooked. For instance, to reduce travel costs, you could use more conferencing and collaboration technologies. To reduce mobile bills, you can look to FMC and getting mobile traffic onto global VPNs as soon as possible.

Cansfield recommends that companies do more to automate and integrate their supply chains upwards and downwards. And supply chains are also the answer to innovation too - work with your partners to develop new products, go-to-market strategies and figure out ways to dramatically remove costs from processes. "A company is only as strong as its ecosystem."

It's all pretty simple stuff but according to Cansfield this was overlooked during the growth years, with chief execs so focussed on sales and the top line that they neglected the bottom line. So the message is: use the downturn to review and revise all processes. Let the problems lead (or solutions to them) and let the technology follow.

virtualization blunts server sales

filtering.gif
Proof, if any more were needed, that virtualization is taking off and delivering on its promise of reducing the number of servers required has been provided by analyst firm IDC. The company's Worldwide Quarterly Server Tracker found that factory revenue declined 24.5% year-on-year in the first quarter of this year. Although some of the blame for this can be placed at the door of the recession, this represents the third successive quarter of year-on-year revenue decline. At US$9.9bn, the quarter also showed the lowest server revenue since IDC began tracking 12 years ago.

Demand slackened across the board with volume systems revenues slipping 30.5%and midrange enterprise demand weakening by 13.6%. The slowdown also reached the high-end enterprise segment, which saw revenues fall by 19.5%. This is the second consecutive quarter and only the second time since 2002 that all three server segments have experienced a year-over-year revenue decline in the same quarter.

Daniel Harrington, a research analyst with IDC reckons that larger enterprises are turning to virtualization, consolidating more workloads per physical server as an alternative to buying new servers. He also reported that most server purchases in the first quarter were made out of necessity, especially by small and medium-sized businesses that needed more server capacity.

Ethernet, MPLS and IP dominate the WAN

Which enterprise network technologies are most common?
Over the last five years, two technologies have come to dominate fixed enterprise networks: multiprotocol label switching (MPLS) and Ethernet. Demand for both MPLS IPVPN and Ethernet services are booming. Analyst Infonetics says that worldwide Ethernet service revenue grew 33% to $12.5 billion in 2007, and IP MPLS VPN service revenue grew 20% to $13 billion; it predicts that both will grow strongly through to 2011.

What's so special about MPLS and Ethernet?
MPLS was first conceived in the late 1990s to improve the performance of IP traffic over the network. For this it uses classes of service that allow enterprises to put time-sensitive applications such as VoIP in a priority class, and batch traffic such as email in a 'best-effort' class. MPLS IP VPNs are popular with enterprises because they offer quality of service and security guarantees, and allow them to utilize a single network for all voice, video and data traffic. More recently, advances in Ethernet technology have seen it make major inroads into the enterprise WAN. The main drivers for Ethernet's popularity are: ubiquity, which makes equipment economical; flexibility, as enterprises can scale bandwidth up and down easily; and its support for IP.

Why is IP fundamental to enterprise networking?
Internet Protocol (IP) is a protocol for communicating data over a packet-switched network and is the fundamental language of Internet communications. The advantage of packet switching is that it allows multiple transmissions to share the same network, so that one 'converged' network can carry all information and services - voice, data, and video. It is simpler and more economical for a large enterprise to run operations for the entire organization on a single network. 

What is a virtual private network (VPN)?
The virtual in a VPN allows you to create a private network within a much larger network, such as the Internet or a service provider's backbone. There are two types of VPNs: trusted VPNs and secure VPNs. MPLS IP VPNs are an example of the former. They allow service providers to create virtual circuits within their IP network and sell these as VPN services. MPLS isolates the traffic streams from one another so that customers can share the same network, much like legacy ATM or Frame Relay services.

What is the difference between an access and core network?
A multi-site enterprise WAN will typically comprise an access and a core network. Also called backbones, core networks such as MPLS IP VPNs and Ethernet consist of the service providers' high-speed worldwide infrastructure, to which it provides access through a series of points-of-presence (PoP). Access networks are essentially the link between those core network PoP and the enterprise site. Network technologies used here include xDSL, T1/E1, fiber, Ethernet, ISDN, dial-up, wireless networks such as WiMax and microwave, and satellite.

Enterprises look to network service providers for application optimization

A report published by Ovum earlier this summer found that businesses are still struggling to deliver decent application performance over their network. The analyst spoke to senior IT professionals in 150 large enterprises in Europe and the US about how their WAN is coping with the ever-greater demands from applications. It found that the vast majority were starting to look to their network service provider for application optimization services.

The report was sponsored by Ipanema and the top-level findings are in its press release. Although 78% of respondents admitted that poorly performing networked applications would have a serious impact on their business, less than half of them had confidence in their tools to maintain high performance. According to author of the report and Ovum principal analyst Peter Hall, “these results suggest that the current approach has some significant limitations.”

In face of the increasing complexity of application acceleration technology and tools, between 65% and 80% of respondents were considering out-tasking application optimization to their network service provider. Areas they felt service providers could contribute most were in: guaranteeing the performance of business-critical applications and acceleration technologies to reduce bandwidth usage and delays. The full report can be downloaded after registration via Ipanema from here.
